Abstract
The utility model relates to the technical field of tapered roller bearings, in particular to a double-row tapered roller bearing, which comprises an outer ring, inner rings, roller and a retaining frame. The row number of the roller is two, the outer ring is a whole, the smaller end faces of the two inner rings are close, a separating ring is arranged between the smaller end faces of the two inner rings, a tapered inner ring assembly composed of the roller and a retaining frame assembly is a separable structure. The double-row tapered roller bearing can be used in a hub of a front wheel of a vehicle, thereby being strong in carrying capacity and large in load-bearing capacity. Friction between the roller and flanges of a sleeved ring is small, and the double-row tapered roller bearing is suitable for high speed rotation.
Description
Technical field
The utility model relates to the tapered roller bearing technical field, especially a kind of double-row conical bearing.
Background technique
In industries such as automobile, milling train, mine, metallurgy, plastics machineries; Can require has supporting design bearing, often can use tapered roller bearing, mainly bears with the footpath that radially is the master, axial connected load; Bearing load carrying capacity depends on the raceway angles of outer ring, and the big more bearing capacity of angle is big more.The overwhelming majority adopts single-row tapered roller bearing, can't tackle the high-revolving requirement of high load, because bearing capacity is lower, has certain influence in usability with on working life, and in addition, play needs the user to adjust when mounted, and is cumbersome.
The model utility content
The technical problem that the utility model will solve is: for solving the deficiency of existing technology, a kind of tapered roller bearing of biserial is provided.
The utility model solves the technological scheme that its technical problem adopted: a kind of double-row conical bearing, comprise the outer ring, and inner ring, roller and retainer, the columns of roller are two row, and the outer ring is an integral body, and two inner ring small end faces are close, and the centre is provided with spacer ring.The cone assembly that the inner ring of roller and retainer assembly is formed is a separable structure.Double-row conical bearing adopts the steel plate punching press.The double-row conical bearing play is given according to customer requirements when product export, must user's adjustment.
The beneficial effect of the utility model is, the double-row conical bearing of the utility model can be used in the front-wheel hub of car, and bearing capacity is stronger, and load carrying capacity is big, and roller and the friction of lasso rib are little, are suitable for high speed rotating.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
1. outer rings among the figure, 2. inner ring, 3. roller.
Embodiment
Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the schematic representation of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of double-row conical bearing as shown in Figure 1 comprises outer ring 1, inner ring 2, and roller 3 and retainer, the columns of roller 3 are two row, and outer ring 1 is an integral body, and two inner ring 2 small end faces are close, and the centre is provided with spacer ring.Roller 3 is a separable structure with cone 2 assemblies that the inner ring 2 of retainer assembly is formed.Double-row conical bearing adopts the steel plate punching press, basket shape retainer or the car system of employing entity post cage.The double-row conical bearing play is given according to customer requirements when product export, must user's adjustment.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
